Description

Technical Field

[0001] This invention relates to a method for manufacturing onion pulp for papermaking and capsules, and more specifically, to a method for manufacturing environmentally friendly and durable plant-based onion pulp using onions and jelly powder. Background Technology

[0002] On Earth, forests play a crucial role in mitigating climate change by absorbing carbon dioxide from the atmosphere, and they serve as habitats for a wide variety of organisms, forming ecosystems upon which numerous species depend. Furthermore, forests influence crop production while protecting and maintaining soil, and they not only filter and purify water but also provide economic livelihoods and cultural value for many people.

[0003] If forests that provide these global values ​​are cleared, their natural functions will decline, biodiversity will decrease, and species extinction and ecosystem instability will occur. Soil erosion will negatively impact crop production and exacerbate water pollution, and social and economic instability will lead to industrial crises. To prevent these risks and crises and protect forests, it is crucial to strengthen forest protection policies and manage forests sustainably.

[0004] Furthermore, as humanity has entered civilized society, the need and importance of continuously challenging and researching "new papermaking"—a product created through deforestation—has been emphasized through a shift in innovative thinking. Paper pulp is one of the materials used to manufacture paper and paper products, and it is typically made by processing wood such as trees.

[0005] Paper pulp can be divided into chemical pulp, which is produced by chemical methods, and mechanical pulp, which is produced by mechanical methods. Chemical pulp can be used when producing higher quality paper, while mechanical pulp has excellent strength and durability and can be used as a lower-cost pulp.

[0006] However, these paper manufacturing industries have a significant environmental impact, so the recent reality is that using more environmentally friendly methods to produce paper pulp has become a major issue in the industry. Efforts are underway to fully utilize renewable resources in the production of paper pulp or to minimize pollution generated during chemical processing.

[0007] In addition, capsule pulp is one of the main materials used in the manufacture of pharmaceutical capsules, which contain medicines. It can be used to manufacture capsules of various shapes and sizes used in the pharmaceutical industry. This capsule pulp is made by processing wood fibers into sheets and then shaping them for capsule production. In particular, because capsule pulp is used as an important material in the pharmaceutical industry, it must be chemically stable, environmentally friendly, and able to maintain appropriate strength.

[0008] In addition, existing pharmaceutical capsules are made using gelatin, which is based on proteins obtained from animal cartilage, skin, bones, etc. However, this poses the problem of indigestion in the body when the capsule is ingested, and it is also unsuitable for vegetarians. Summary of the Invention

[0009] Technical issues The present invention was developed in view of the problems described above. The present invention uses onions instead of trees to make pulp and uses the pulp to make paper, thereby having the advantages of protecting forests in the environment and contributing to climate change and ecosystem maintenance.

[0010] Furthermore, economically, this invention uses onions to produce pulp, thereby saving processing costs, cultivation time, and production speed, thus greatly improving production efficiency. In terms of social value, it protects the Earth's forests, and unlike animal-derived capsules primarily made from animal skins, this invention is environmentally friendly in protecting animals and preventing harm to the natural environment. Moreover, it decomposes rapidly in the human digestive system, making it safer, especially for vegans and vegetarians, thus improving their quality of life and laying the foundation for a better future for humanity.

[0011] In addition, this invention can also serve as a foundational technology in the agricultural sector, playing a vital role in providing jobs and producing food.

[0012] Specifically, the present invention mixes jelly powder and pulverized onion to produce onion pulp, thereby providing a method for manufacturing onion pulp for papermaking and capsules that is both more environmentally friendly and ensures the durability of the pulp.

[0013] Furthermore, regarding the method for manufacturing onion pulp for papermaking and capsules according to an embodiment of the present invention, by experimentally designing the proportion of jelly powder to an optimal value, a method for manufacturing onion pulp for papermaking and capsules that can ensure cohesion and tensile strength can be provided.

[0014] Furthermore, according to an embodiment of the present invention, the method for manufacturing onion pulp for papermaking and capsules not only removes the unpleasant odor of onions by removing the sugar and sulfur from the onions, but also makes it easier to separate the dried onion flakes from the forming mold, thereby providing a method for manufacturing onion pulp for papermaking and capsules with improved performance.

[0015] Furthermore, according to one embodiment of the present invention, the method for manufacturing onion pulp for papermaking and capsules makes full use of the inherent components of onions, thereby providing a method for manufacturing onion pulp for capsules in which the capsules themselves can provide functions beneficial to the human body.

[0017] The aforementioned jelly powder can be composed of at least one of mung bean jelly powder, acorn jelly powder, and agar jelly powder.

[0018] When manufacturing onion pulp for papermaking, the ratio of the above-mentioned jelly powder to the above-mentioned purified water can be 1:60. When manufacturing onion pulp for capsules, the ratio of the above-mentioned jelly powder to the above-mentioned purified water can be 1:70.

[0019] The steps for generating the onion powder described above may include: compressing and pulverizing the onion once; pulverizing the pulverized onion a second time; and washing the pulverized onion with purified water.

[0020] The step of drying the final mixture after molding may include drying the final mixture at a temperature of 65 degrees Celsius for more than 1 hour and 30 minutes and less than 2 hours and 30 minutes.

[0021] Invention Effects The method for manufacturing onion pulp for papermaking and capsules according to the present invention mixes jelly powder and pulverized onion to produce onion pulp, thereby having the advantages of being more environmentally friendly and ensuring the durability of the pulp.

[0022] Furthermore, according to an embodiment of the present invention, the method for manufacturing onion pulp for papermaking and capsules optimizes the proportion of jelly powder through experiments, thereby ensuring cohesion and tensile strength.

[0023] In addition, according to an embodiment of the present invention, the method for manufacturing onion pulp for papermaking and capsules removes sugar and sulfur from onions, thereby not only removing the unpleasant odor and toxicity caused by the sulfur components of onions, but also removing a certain amount of sugar components, thus having the advantage of improving performance, making it easy to separate the dried onion flakes from the molding die or Teflon film.

[0024] Furthermore, according to an embodiment of the present invention, the method for manufacturing onion pulp for papermaking and capsules makes full use of the inherent components of onions such as quercetin, vitamin C, and potassium, thereby having the advantage that the capsules themselves can provide functions that are beneficial to the human body.

[0031] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0032] Figure 1 This is a flowchart illustrating a method for manufacturing onion pulp for papermaking and capsules according to an embodiment of the present invention. Figure 2 This diagram illustrates a method for removing sugar and sulfur from onions in a method for manufacturing onion pulp for papermaking and capsules according to an embodiment of the present invention. Figure 3 This is a diagram illustrating another method for removing sugar and sulfur from onions in a method for manufacturing onion pulp for papermaking and capsules according to an embodiment of the present invention.

[0033] Reference Figure 1 According to an embodiment of the present invention, a method for manufacturing onion pulp for papermaking and capsules can be carried out using jelly powder and crushed onion through multiple steps.

[0034] Figure 1 The method for manufacturing onion pulp for papermaking and for capsules described herein only describes the common parts in manufacturing onion pulp for papermaking and onion pulp for capsules according to one embodiment of the present invention. The method for manufacturing onion pulp for papermaking and the method for manufacturing onion pulp for capsules according to the present invention differ in elements such as the proportion of jelly powder, the size of the compressed and crushed onion particles, and the final thickness of the onion pulp.

[0035] In addition, the term "onion pulp" used in this invention refers to the form of a rolled-up onion "sheet" that has been shaped and dried. The method for forming onion sheets will be described in detail below.

[0036] Hereinafter, a method for manufacturing onion pulp for papermaking according to an embodiment of the present invention will be described.

[0037] Specifically, a method for manufacturing onion pulp for papermaking according to an embodiment of the present invention may include a step S110 of removing sugars and sulfur from onions. More specifically, step S110 of removing sugars and sulfur from onions can be achieved through... Figure 2 The method shown is to remove the sugars and sulfur from onions using the dripping phenomenon and the principle of osmotic pressure, or it can be done using... Figure 3 The method shown is to remove the sugars and sulfur from the onion by physically breaking down the onion's tissues using a compression shredder.

[0038] For example, such as Figure 2 As shown, the step S110 of the method for removing sugar and sulfur from onions according to the present invention, which utilizes the dripping phenomenon and the principle of osmotic pressure, may include the step S111 of cutting the onion. The dripping phenomenon refers to the phenomenon in which water and various components flow out of a particular object during the thawing process after freezing.

[0039] Specifically, step S111 of cutting the onion may include cutting the onion into a quadrilateral shape. In this case, the width of the cut onion pieces may be 0.1 mm or more and 1.5 mm or less.

[0040] Subsequently, step S110 of removing sugar and sulfur from onions according to the method of removing sugar and sulfur from onions by utilizing the dripping phenomenon and the principle of osmotic pressure may include step S112 of freezing the onions.

[0041] More specifically, step S112 of freezing onions may include adding purified water to the cut onions and slowly freezing them at a temperature below -18 degrees Celsius for more than 2 days. With slow freezing and thawing, more onion tissue is damaged, the texture of the onions becomes softer when dried, and the removal of sugar and sulfur components increases rapidly.

[0042] However, the embodiments of the present invention are not limited thereto. Step S112 of freezing onions can also be specifically implemented as a step of slowly freezing the cut onions at a temperature below -18 degrees Celsius for more than 2 days without adding pure water.

[0043] Furthermore, in step S112 of freezing onions according to an embodiment of the present invention, the freezing time of the onions may vary depending on the desired amount of sugar and sulfur removal.

[0044] For example, in step S112 of freezing onions according to an embodiment of the present invention, the onions are rapidly frozen to form small, dense ice crystals, thereby minimizing cell wall damage. Furthermore, in the case of rapid freezing, less moisture is lost during thawing, thus reducing the amount of sugar and sulfur removed from the onions compared to non-rapid freezing.

[0045] Furthermore, in step S112 of freezing onions according to one embodiment of the present invention, the onions are frozen at low speed, resulting in the formation of large, low-density ice crystals, which increases cell wall damage. Therefore, under low-speed freezing, more water is lost during thawing, and consequently, more sugars and sulfur are removed from the onions compared to rapid freezing.

[0046] Subsequently, step S110 of removing sugar and sulfur from onions according to the method of removing sugar and sulfur from onions by utilizing the dripping phenomenon and the principle of osmotic pressure may include step S113 of thawing frozen onions.

[0047] Subsequently, step S110 of removing sugar and sulfur from onions according to the method of removing sugar and sulfur from onions by utilizing the dripping phenomenon and the principle of osmotic pressure may include step S114 of compressing and crushing the thawed onions.

[0048] Step S114, which involves compressing and pulverizing thawed onions, may include pulverizing the onions into a predetermined size. The particle size of the pulverized onion used in papermaking onion pulp according to an embodiment of the present invention may be formed to have a width of 0.8 mm or more and 1.5 mm or less.

[0049] As described below, the particle size of the onion pulverizer used in the capsule onion pulp according to an embodiment of the present invention can be formed to have a width of 0.1 mm or more and 0.8 mm or less, which is different from the particle size of the onion pulverizer used in the papermaking onion pulp according to an embodiment of the present invention.

[0050] Therefore, the method for manufacturing onion pulp according to the present invention can form different particle sizes of onion pulverizers according to the intended use of the onion pulp, thereby enabling the onion pulp to have different tensile strengths depending on the intended use.

[0051] Furthermore, step S114 of compressing and pulverizing thawed onions may include adding salt to induce the outflow of water due to osmotic pressure, as well as the rapid outflow of sugar and sulfur components. More specifically, in step S114 of compressing and pulverizing thawed onions, salt may be added to the pulverized onions to induce the expulsion of sugar and sulfur from the onions using the principle of osmotic pressure. Therefore, step S110 of removing sugar and sulfur according to the present invention can remove sugar and sulfur from onions by thawing and pulverizing frozen onions.

[0052] In addition, such as Figure 3 As shown, step S110 of removing sugar and sulfur from onions by physically destroying the tissue of onions using a compression pulverizer according to the present invention may include step S115 of compressing and pulverizing the onions in one step.

[0053] More specifically, step S115, which involves compressing and pulverizing the onion in one pass, may include removing the onion skin and pulverizing the uncooked raw onion using a wet compression pulverizer. In this case, the width of the pulverized onion particles may be 1.4 mm or more and 1.6 mm or less in length. More preferably, the width of the pulverized onion particles may be 1.5 mm.

[0054] Subsequently, step S110 of removing sugars and sulfur from onions by physically breaking down the onion tissue using a compression pulverizer according to the present invention may include step S116 of secondary pulverizing of the onions. In this case, the size of the secondary pulverized onion particles may be formed to have a width of 0.8 mm or more and 1.2 mm or less.

[0055] As described below, the particle size of the secondary onion pulverizer used in onion pulp for capsules according to an embodiment of the present invention can be formed to have a width of 0.1 mm or more and 0.8 mm or less, which is different from the particle size of the onion pulverizer used in onion pulp for papermaking according to an embodiment of the present invention.

[0056] Therefore, the method for manufacturing onion pulp according to the present invention can form different particle sizes of onion pulverizers according to the intended use of the onion pulp, thereby enabling the onion pulp to have different tensile strengths depending on the intended use.

[0057] Subsequently, step S110 of removing the sugar and sulfur from the onion by physically breaking down the onion tissue using a compression pulverizer according to the present invention may include step S117 of washing the pulverized onion with purified water. Step S117 of washing the pulverized onion with purified water may include step S117 of washing the pulverized onion with brine.

[0058] More specifically, according to the present invention, step S110, which physically destroys the tissue of the onion by a compression crusher to remove sugar and sulfur, can wash away the sugar and sulfur removed from the onion along with the water during crushing by step S117, which involves washing the crushed onion with pure water, thereby enabling the removal of sugar and sulfur from the onion.

[0059] Furthermore, in step S110 of the present invention, which removes sugar and sulfur from onions by physically destroying the onion tissue using a compression pulverizer, the particle size of the onion pulverizer can vary depending on the ratio of sugar and sulfur to be removed.

[0060] Therefore, as described above, the method for manufacturing onion pulp for papermaking according to the present invention removes the sugar content of onions in a variety of ways, thereby enabling the onion flakes dried on a molding die or Teflon film to be easily separated from the molding die.

[0061] If onion slices are dried in a molding die without removing the sugar from the onions, the sugar content can cause the onion slices to stick to the molding die when separating them from the Teflon film, thus compromising the quality of the onion slices.

[0062] Therefore, the present invention enables onion slices to be easily separated from the forming mold by various methods of removing sugar components from onions, and has the technical effect of improving the quality of onion pulp formed by winding onion slices.

[0063] In addition, the present invention removes sulfur from onions, thereby achieving the technical effect of preventing onion pulp used in papermaking from emitting the characteristic odor of onions.

[0064] Subsequently, a method for manufacturing onion pulp for papermaking according to an embodiment of the present invention may include step S120 of mixing and stirring jelly powder with water in a prescribed ratio.

[0065] More specifically, step S120, which involves mixing and stirring the mung bean jelly powder with purified water in a prescribed ratio, may include mixing the mung bean jelly powder with purified water in a ratio of 1:50 to 1:62.

[0066] If the mung bean jelly powder is composed in a larger proportion than the above, the hardening process becomes severe during the drying of the mung bean jelly powder and onion pulverizer, thereby weakening the tensile strength of the onion pulp for papermaking.

[0067] Therefore, the present invention may include the step of mixing and stirring mung bean jelly powder with purified water at a ratio of 1:60 to specifically achieve the tensile strength most suitable for papermaking. The mung bean jelly powder may have the property of solidifying upon mixing with water. This mung bean jelly powder may contain protein components extracted from seaweed such as kelp or wakame.

[0068] In addition, this mung bean jelly powder can be mainly composed of polysaccharides such as amylose or amylopectin, or proteins, and exists in a powdered state as fine particles.

[0069] Therefore, when mung bean jelly powder is mixed with water such as purified water, the mung bean jelly powder can be absorbed by the water and dispersed evenly. At this time, the protein components of mung bean starch or acorn starch interact with the water, causing the mung bean jelly powder aqueous solution to gel.

[0070] Therefore, the state of the mung bean jelly powder solution changes through gelation into a branched polymer with inter-chain linkages, and as the linkages continue, it changes into a larger branched polymer, thus it can be composed of a single polymer.

[0071] Furthermore, the jelly powder according to the present invention is not limited to mung bean jelly powder containing mung bean starch, but can also be specifically implemented as acorn jelly powder containing acorn starch. Additionally, the jelly powder according to the present invention can also be specifically implemented as agar jelly powder. In this case, the proportion of acorn jelly powder can also be the same as the proportion of mung bean jelly powder.

[0072] Subsequently, a method for manufacturing onion pulp for papermaking according to an embodiment of the present invention may include step S130 of heating a primary mixture of jelly powder and purified water.

[0073] More specifically, step S130 of heating the mixture of jelly powder and purified water may include heating the mixture to 100 degrees Celsius, then heating for another 5 seconds after reaching 100 degrees Celsius and then stopping the heating.

[0074] Specifically, if the heating time of the jelly powder is too long, the starch molecules in the jelly powder, which is made of mung bean jelly powder or acorn jelly powder, will decompose. This will weaken the binding between the onion pulverizer and the starch in the jelly powder, resulting in a decrease in the cohesiveness, elasticity, and tensile strength of the onion pulp as the final product.

[0075] Therefore, the present invention adjusts the heating time of the primary mixture of jelly powder and purified water within a certain range, thereby achieving the technical effect of ensuring the cohesiveness, elasticity and tensile strength of onion pulp.

[0076] Subsequently, a method for manufacturing onion pulp for papermaking according to an embodiment of the present invention may include step S140 of mixing a primary mixture of jelly powder and purified water with onion pulverizer in which sugar and sulfur have been removed.

[0077] More specifically, step S140, which involves mixing the initial mixture of jelly powder and purified water with the onion powder that has undergone sugar and sulfur removal, may include a stirring step within a container to allow the residual sugar components in the onion powder and the starch components of the jelly powder to combine. At this point, the onion powder may be added at 80% by weight of the initially added purified water and stirred.

[0078] In addition, in this case, regarding the onion powder, through step S110 to remove sugar and sulfur, the sugar and sulfur components are removed to a certain level, and it can be stirred with a primary mixture containing jelly powder and purified water at a moisture content of 120%.

[0079] Subsequently, a method for manufacturing onion pulp for papermaking according to an embodiment of the present invention may include step S150 of placing the stirred final mixture on a molding die for molding. More specifically, the final mixture may be defined as containing stirred onion shreds, agar powder, and purified water.

[0080] Specifically, in the case of onion pulp for papermaking according to the present invention, step S150, which involves placing the final mixture on a molding die for molding, may include the step of forming onion flakes with a thickness of 0.4 mm or more and 0.8 mm or less.

[0081] Subsequently, a method for manufacturing onion pulp for papermaking according to an embodiment of the present invention may include step S160 of drying the formed onion flakes.

[0082] More specifically, step S160 of drying the formed onion slices may include drying the onion slices at a temperature of 65 degrees Celsius for at least 1 hour and 30 minutes and less than 2 hours and 30 minutes. More preferably, the onion slices may be dried for 2 hours.

[0083] Therefore, by appropriately adjusting the drying temperature and drying time of the onion sheets according to the method for manufacturing onion pulp for papermaking according to the present invention, the cohesiveness, elasticity, and tensile strength of the onion sheets can be formed to a degree suitable for papermaking.

[0084] The following describes a method for manufacturing onion pulp for capsules according to an embodiment of the present invention.

[0085] Specifically, a method for manufacturing onion pulp for capsules according to an embodiment of the present invention may include step S110 of removing sugar and sulfur from onions.

[0086] More specifically, step S110, which removes the sugar and sulfur from onions, can be achieved through... Figure 2 The method shown is to remove the sugars and sulfur from onions using the dripping phenomenon and the principle of osmotic pressure, or it can be done using... Figure 3 The method shown is to remove the sugars and sulfur from the onion by physically breaking down the onion's tissues using a compression shredder.

[0087] For example, such as Figure 2 As shown, the step S110 of the method for removing sugar and sulfur from onions according to the present invention, which utilizes the dripping phenomenon and the principle of osmotic pressure, may include the step S111 of cutting the onion.

[0088] The dripping phenomenon refers to the outflow of water and various components from a frozen object during the thawing process.

[0089] Specifically, step S111 of cutting the onion may include cutting the onion into a quadrilateral shape. In this case, the width of the cut onion pieces may be 0.1 mm or more and 1.5 mm or less.

[0090] Subsequently, step S110 of removing sugar and sulfur from onions according to the method of removing sugar and sulfur from onions by utilizing the dripping phenomenon and the principle of osmotic pressure may include step S112 of freezing the onions.

[0091] More specifically, step S112 of freezing onions may include adding purified water to the cut onions and slowly freezing them at a temperature below -18 degrees Celsius for more than 2 days.

[0092] However, the embodiments of the present invention are not limited thereto. Step S112 of freezing onions can also be specifically implemented as a step of slowly freezing the cut onions at a temperature below -18 degrees Celsius for more than 2 days without adding pure water.

[0093] Furthermore, in step S112 of freezing onions according to an embodiment of the present invention, the freezing time of the onions may vary depending on the desired amount of sugar and sulfur removal.

[0094] For example, in step S112 of freezing onions according to an embodiment of the present invention, the onions are rapidly frozen to form small, dense ice crystals, thereby minimizing cell wall damage. Furthermore, in the case of rapid freezing, less moisture is lost during thawing, thus reducing the amount of sugar and sulfur removed from the onions compared to non-rapid freezing.

[0095] Furthermore, in step S112 of freezing onions according to one embodiment of the present invention, the onions are frozen at low speed, resulting in the formation of large, low-density ice crystals, which increases cell wall damage. Therefore, under low-speed freezing, more water is lost during thawing, and consequently, more sugars and sulfur are removed from the onions compared to rapid freezing.

[0096] Subsequently, step S110 of removing sugar and sulfur from onions according to the method of removing sugar and sulfur from onions by utilizing the dripping phenomenon and the principle of osmotic pressure may include step S113 of thawing frozen onions.

[0097] Subsequently, step S110 of removing sugar and sulfur from onions according to the method of removing sugar and sulfur from onions by utilizing the dripping phenomenon and the principle of osmotic pressure may include step S114 of compressing and crushing the thawed onions.

[0098] Step S114, which involves compressing and pulverizing thawed onions, may include pulverizing the onions into a predetermined size. The particle size of the pulverized onion used in capsule-grade onion pulp according to an embodiment of the present invention may be formed to have a width of 0.1 mm or more and 0.8 mm or less.

[0099] As described above, the particle size of the onion pulverizer used in the capsule onion pulp according to an embodiment of the present invention can be formed to have a smaller particle size than that of the onion pulverizer used in the papermaking onion pulp according to an embodiment of the present invention.

[0100] Therefore, the method for manufacturing onion pulp according to the present invention can form different particle sizes of onion pulverizers according to the intended use of the onion pulp, thereby enabling the onion pulp to have different tensile strengths depending on the intended use.

[0101] Additionally, step S114 of compressing and pulverizing thawed onions may include adding salt to induce the outflow of water due to osmotic pressure. More specifically, in step S114 of compressing and pulverizing thawed onions, salt may be added to the pulverized onions to induce the expulsion of sugars and sulfur from the onions using the principle of osmotic pressure.

[0102] Therefore, step S110 of removing sugar and sulfur according to the present invention can remove sugar and sulfur from onions by thawing frozen onions and crushing them.

[0103] In addition, such as Figure 3 As shown, step S110 of removing sugar and sulfur from onions by physically destroying the tissue of onions using a compression pulverizer according to the present invention may include step S115 of compressing and pulverizing the onions in one step.

[0104] More specifically, step S115, which involves compressing and pulverizing the onion in one pass, may include removing the onion skin and pulverizing the uncooked raw onion using a wet compression pulverizer. In this case, the width of the pulverized onion particles may be 1.4 mm or more and 1.6 mm or less in length. More preferably, the width of the pulverized onion particles may be 1.5 mm.

[0105] Subsequently, step S110 of removing sugars and sulfur from onions by physically breaking down the onion tissue using a compression pulverizer according to the present invention may include step S116 of further pulverizing the onions. In this case, the size of the pulverized onion particles may be formed to have a width of 0.1 mm or more and 0.8 mm or less.

[0106] Therefore, the method for manufacturing onion pulp according to the present invention can form different particle sizes of onion pulverizers according to the intended use of the onion pulp, thereby enabling the onion pulp to have different tensile strengths depending on the intended use.

[0107] Subsequently, step S110 of removing sugar and sulfur from onions by physically destroying the onion tissue using a compression pulverizer according to the present invention may include step S117 of washing the pulverized onions with purified water.

[0108] More specifically, according to the present invention, step S110, which physically destroys the tissue of the onion by a compression crusher to remove sugar and sulfur, can wash away the sugar and sulfur removed from the onion along with the water during crushing by step S117, which involves washing the crushed onion with pure water, thereby enabling the removal of sugar and sulfur from the onion.

[0109] Furthermore, in step S110 of the present invention, which removes sugar and sulfur from onions by physically destroying the onion tissue using a compression pulverizer, the particle size of the onion pulverizer can vary depending on the ratio of sugar and sulfur to be removed.

[0110] Therefore, as described above, the method for manufacturing onion pulp for capsules according to the present invention removes the sugar content of onions in a variety of ways, thereby enabling the onion flakes dried on a molding die or Teflon film to be easily separated from the molding die.

[0111] If onion slices are dried in a molding die without removing the sugar from the onions, the sugar content can cause the onion slices to stick to the molding die when they are separated from the die, thus compromising the quality of the onion slices.

[0112] Therefore, the present invention enables onion slices to be easily separated from the forming mold by various methods of removing sugar components from onions, and has the technical effect of improving the quality of onion pulp formed by winding onion slices.

[0113] In addition, the present invention removes sulfur from onions, thereby achieving the technical effect of preventing the onion pulp used in the capsules from emitting the characteristic odor of onions.

[0114] Specifically, in the case of capsules made from onion pulp, as a food intended for oral consumption, the sulfur removal process is also an important factor in terms of usability.

[0115] Subsequently, a method for manufacturing onion pulp for capsules according to an embodiment of the present invention may include step S120 of mixing and stirring jelly powder with water in a prescribed ratio.

[0116] More specifically, step S120, which involves mixing and stirring the mung bean jelly powder with purified water in a prescribed ratio, may include mixing the mung bean jelly powder with purified water in a ratio of 1:63 to 1:83.

[0117] If the mung bean jelly powder is composed in a larger proportion than described above, the bonding between the mung bean jelly powder and the pulverized onion becomes stronger, thereby weakening the tensile strength of the onion pulp for papermaking. Therefore, the present invention can include a step of mixing and stirring the mung bean jelly powder and purified water at a ratio of 1:70, which differs from the method for manufacturing onion pulp for papermaking, to specifically achieve the strength most suitable for use in capsules.

[0118] Mung bean jelly powder can have the property of solidifying when mixed with water. This type of mung bean jelly powder may contain protein components extracted from seaweed such as kelp or wakame.

[0119] Furthermore, this mung bean jelly powder can be primarily composed of polysaccharides such as amylose or amylopectin, or proteins, and exists in a powdered, finely granulated state. Therefore, when mung bean jelly powder is mixed with water such as purified water, the powder can be absorbed and evenly dispersed. At this point, the protein components of mung bean starch and acorn starch interact with the water, causing the mung bean jelly powder aqueous solution to gel.

[0120] Therefore, the state of the mung bean jelly powder solution changes through gelation into a branched polymer with inter-chain linkages, and as the linkages continue, it changes into a larger branched polymer, thus it can be composed of a single polymer.

[0121] Furthermore, the jelly powder according to the present invention is not limited to mung bean jelly powder, but can also be specifically implemented as acorn jelly powder. In this case, the proportion of acorn jelly powder can also be the same as that of mung bean jelly powder.

[0122] Subsequently, a method for manufacturing onion pulp for capsules according to an embodiment of the present invention may include step S130 of heating a primary mixture of agar powder and purified water.

[0123] More specifically, step S130 of heating the mixture of jelly powder and purified water may include heating the mixture to 100 degrees Celsius, then heating for another 5 seconds after reaching 100 degrees Celsius and then stopping the heating.

[0124] Specifically, if the heating time of the jelly powder is too long, the starch molecules in the jelly powder, which is made of mung bean jelly powder or acorn jelly powder, will decompose. This will weaken the binding between the onion pulverizer and the starch in the jelly powder, resulting in a decrease in the cohesiveness, elasticity, and tensile strength of the onion pulp as the final product.

[0125] Therefore, the present invention adjusts the heating time of the primary mixture of jelly powder and purified water within a certain range, thereby achieving the technical effect of ensuring the cohesiveness, elasticity and tensile strength of onion pulp.

[0126] Subsequently, a method for manufacturing onion pulp for capsules according to an embodiment of the present invention may include step S140 of mixing a primary mixture of jelly powder and purified water with onion pulverizer in which sugar and sulfur have been removed.

[0127] More specifically, step S140, which involves mixing the initial mixture of jelly powder and purified water with the onion powder that has undergone sugar and sulfur removal, may include a stirring step within a container to allow the residual sugar components in the onion powder and the starch components of the jelly powder to combine. At this point, the onion powder may be added at 80% by weight of the initially added purified water and stirred.

[0128] In addition, in this case, regarding the onion powder, through step S110 to remove sugar and sulfur, the sugar and sulfur components are removed to a certain level, and it can be stirred with a primary mixture containing jelly powder and purified water at a moisture content of 120%.

[0129] Subsequently, a method for manufacturing capsules using onion pulp according to an embodiment of the present invention may include step S150 of placing the stirred final mixture onto a molding die for molding. More specifically, the final mixture may be defined as comprising stirred onion pulverized material, agar powder, and purified water.

[0130] Specifically, in the case of onion pulp for capsules according to the present invention, step S150, which involves placing the final mixture on a molding die for molding, may include the step of forming onion flakes with a thickness of 0.1 mm or more and 0.3 mm or less. Therefore, the onion pulp for capsules according to the present invention can be molded to a thickness thinner than that of onion pulp for papermaking, thereby forming capsules smaller than paper.

[0131] Subsequently, a method for manufacturing onion pulp for capsules according to an embodiment of the present invention may include step S160 of drying the formed onion flakes.

[0132] More specifically, step S160 of drying the formed onion slices may include drying the onion slices at a temperature of 65 degrees Celsius for at least 1 hour and 30 minutes and less than 2 hours and 30 minutes. More preferably, the onion slices may be dried for 2 hours.

[0133] Therefore, by appropriately adjusting the drying temperature and drying time of the onion flakes according to the method for manufacturing onion pulp for papermaking according to the present invention, the cohesiveness, elasticity, and tensile strength of the onion flakes can be formed to a degree suitable for use in capsules.

[0134] Therefore, the method for manufacturing onion pulp for papermaking and capsules according to an embodiment of the present invention mixes jelly powder and pulverized onion to manufacture onion pulp, thereby having the advantages of being more environmentally friendly and ensuring the durability of the pulp.

[0135] Furthermore, according to an embodiment of the present invention, the method for manufacturing onion pulp for papermaking and capsules optimizes the proportion of jelly powder through experiments, thereby ensuring cohesion and tensile strength.

[0136] In addition, according to an embodiment of the present invention, the method for manufacturing onion pulp for papermaking and capsules not only removes the unpleasant odor of onions by removing the sugar and sulfur from the onions, but also has the advantage of improving performance, making it easy to separate the dried onion flakes from the molding die or Teflon film.

[0137] Furthermore, according to an embodiment of the present invention, the method for manufacturing onion pulp for papermaking and capsules makes full use of the inherent components of onions, thereby having the advantage that the capsules themselves can provide functions that are beneficial to the human body.
